PEMF Cap at Gerrish MedEsthetics

Support Fuller, Healthier-Looking Hair, Without Pills or Downtime.

The PEMF Cap is a wearable device that uses pulsed electromagnetic field (PEMF) technology to support your body's natural hair-growth processes at the follicle, designed to be worn comfortably for a short daily session. StimuField was co-developed by Dr. Robert Dennis and Dr. Scott Gerrish. It is built on ICES technology developed by Dr. Dennis, while Dr. Gerrish led the clinical research, protocol development, and practical application that helped shape StimuField into its current wearable system.

Co-Developed by Dr. Gerrish

As co-developer of StimuField, Dr. Scott Gerrish brings a physician's understanding of hair biology together with the science behind the device. Disclosure: Dr. Gerrish serves as Chief Medical Officer of StimuSIL, the company behind StimuField, and holds an equity interest in the company.

Why Patients Consider PEMF Cap

When Thinning Hair Starts to Wear on You

Noticing more hair in the brush, a part that keeps widening, or a scalp that shows through where it once did not can quietly chip away at how you feel. Thinning hair often develops gradually, and many people try product after product hoping for something that fits into real life. The frustration is common, and it is rarely for lack of effort.

PEMF Cap Explained

How PEMF Cap Works

The PEMF Cap uses pulsed electromagnetic fields that mimic the body's own electromagnetic signals to help create supportive conditions for hair follicles. Unlike light-based devices, electromagnetic fields can reach the follicle without being blocked by hair, and they are delivered evenly across the scalp. Worn for a short session each day, the device is designed to support the natural repair and regeneration of hair follicle cells over time.

The Daily Routine

What Daily Use Involves

Getting started

Our Clinical Team reviews your hair and scalp, then shows you how to fit the device and wear it comfortably at home.

Brief daily sessions

The cap is worn for a short session each day. There is no heat, sensation, gels, or recovery period, so it fits easily into your day.

Consistency over months

As with most hair therapies, steady, ongoing use over several months gives the technology time to work.

Tracking progress

Changes in hair develop gradually, and the treating clinician can help you track density and shedding over time.

Where This Fits in Your Treatment Strategy

The PEMF Cap addresses hair thinning as part of a broader picture of wellness and self-confidence. It may be considered alongside hormone evaluation and overall wellness care, since hair health often reflects what is happening in the body as a whole. Whether it belongs in your plan is determined at consultation.
